Eucnemidae是一个相对较大的甲虫家族，属于Polyphagan超家族Elateroidea。在新生代沉积中发现了大量的真科昆虫化石，但在中生代的真科昆虫化石记录却很少。本文描述了一种新的拟步甲--大拟步甲Muonabuntorgrandinotalis gen. etsp. nov.，发现于白垩纪中期的缅甸琥珀（约99Ma）。新属类似于现存的Jenibuntor和Euryptychus，具有简单的下节和管状触角9-11，但与后者不同的是其相对较长的前胸背板，弱条纹的鞘翅和大的后基板。本文还对真线虫科的化石记录和分类系统进行了评述。
Eucnemidae is a relatively large beetle family belonging to the polyphagan superfamily Elateroidea. Numerous fossil eucnemids have been reported from Cenozoic deposits, but the Mesozoic record of Eucnemidae is much sparser. Here we describe and figure a new eucnemid beetle, Muonabuntor grandinotalis gen. et sp. nov., discovered from mid-Cretaceous Burmese amber (ca. 99 Ma). The new genus resembles extant Jenibuntor and Euryptychus in having simple hypomera and tubular antennomeres 9–11, but differs from the latter genera by its comparatively longer pronotum, weakly striate elytra, and large metacoxal plates. The fossil record and classification system of Eucnemidae are also reviewed.
